Description

SAFETY CLOSURE AND CONTAINER The present invention relates to safety closures for use on containers.

More particularly, the present invention relates to a safety closure for use on a container, wherein the safety closure and the container are each provided with engageable lucking means which cooperate to seal the container and to inhibit access thereto by individuals of tender years.

It is mell known in the prior art to sealingly affix a safety closure upon the neck portion of a container to prevent unwanted spillage of the contents of the container therefrom. Typically, a gasket liner is positioned within the safety closure which sealingly engages an upper portion of the container neck portion. Alternatively, a sealing plug may be integrally-fonned within the safety closure which resiliently engages the upper portion of the container neck portion to define a sealing fit therebetween. It is therefore desirable to provide a safety closure for use on a container neck portion, wherein the safety closure is sealingly a: cable to the container neck portion to prevent spillage of the contents of be container therefrom.

It is even further known in the prior art for the safety closure and the container neck portion to each include engageable locking means which cooperate to inhibit removal of the safety closure from the container neck portion by individuals of tender years. It is therefore further desirable to provide a safety closure for use on a container neck portion, wherein the safety closure is sealingly affixable to the container neck portion to prevent spillage of the contents of the container therefrom, and wherein the safety closure and the container each include engageable locking means to inhibit removal of the safety closure from the container neck portion by individuals of tender years For e.ample, U.S. Patent No. 3,951,289 to Landen, and U.S. Patent No. 5,449,078 to Akers, each teach a safety closure device being affixable to a container neck portion, wherein the safety closure includes a continuous plug which is engageable with the container neck portion to define a sealing fit therebetween. The continuous plug also serves to bias the safety closure outwardly frown the container neck portion, thereby cooperating with locking means provided on the safety closure and on the container neck portion to inhibit removal of the safety closure from the container by individuals of tender years. However, it has been observed that, where a common element is used as both biasing means and sealing means, seal integrity is oftentimes breached due to the flexure of the common element which is necessary to provide the bias. Thus, it is further desirable to provide a safety closure for sealingly engaging a container neck portion, wherein the safety closure includes biasing means which are separate and independent from sealing means provided thereby.

The present invention is for a safety closure for use on a container, wherein the Safety closure is provided with separate and independent biasing means and sealing means. The safety closure is provided with at least one lug which engages a bayonet provided on a neck portion of the container and which is biased in a "locked" position on the container neck portion by at least one spring member. The spring member flexes against an outer surface of the container nesk portion to provide an upward biasing force to the safety closure, thereby seating the lug into the bayonet and requiring the user to depress the safety closure downwardly against the spring member bias to unseat the lug. The sealing means is preferably an integral plug which is sized to engage an tçpening in the container neck portion. Flexllre of the spring member does not affect the sealing engagement of the plug within the opening.

It is an object of the present invention to provide a safety closure for use on a container neck portion, wherein the safety closure is sealingly affixable to the container neck portion to prevent spillage of the contents of the container therefrom.

It is another object of the present invention to provide a safety closure for use on a container neck portion, wherein the safety closure is sealingly affixable to the container neck portion to prevent spillage of the contents of the container therefrom1 and wherein the safety closure and the container each include enga,geable locking means to inhibit removal of the safety closure from the container neck portion by individuals of tender years.

It is still another object of the present invention to provide a safety closure for stalingly engaging a container neck portion, wherein the safety closure includes biasing means which are separate and independent from sealing marls provided thereby.

These and other objects, features and advantages of the present invention will become apparent to those skilled in the art upon reading the ensuing detailed description in conjunction with the drawings and with reference to title appended claims.

A safety closure according to a preferred embodiment of the present invention includes an end wall and a side wall depending from the end wall.

The side wall has at least one lug projecting therefrom near a lower end thereof, which is engageable with at least one lug-receiving recess provided in the container neck portion. A sealing plug depends from the end wall and is sealingly engageable with a dispensing orifice provided in the container neck portion. At least one spring member depends from the end wall and is resiliently engageable with the container neck portion to bias the safety closure away from the container neck portion.

With reference to Figures 1-4, a container 50 according to a preferred embodiment of the present invention, only an upper portion of which is shown in the Figures, includes a cylindrical body 52 defining a cavity 53 therein for receiving and storing therein a substance, such as, for example, a liquid, dry powder, or a plurality of pills, capsules, tablets or the like. A cylindrical neck portion 54 projects axially upwardly from the body 52 and is connected to the body 52 by ; frusto-conical shoulder 55. A flusto-conical calming portion 56 projects inwardly and upwardly from an upper end of the neck portion 54 and terminates in an upturned cylindrical portion 59. The shoulder 55, the neck portion 54 ad the camming portion 56 each include a passageway 55a, 54a, 56a, respectiuely, therethrough, thereby providing communication between the body cavity 53 and a dispensing orifice 57 provided through an upper end of the calming portion upturned cylindrical portion 59 to permit filling and dispensing of the substance to and from within the cavity 53. The container 50 is preferably constructed from any suitable heat-setting, moldable polymer, such as, for example, polyester, polyethylene, polypropylene or the like, and is formed by any suitable process, such as, for example, injection-molding or the like.

The neek portion 54 includes at least one integrally-f6rmed, radiallyraised bayonet 60, and preferably, four bayonets 60 annularly spaced equidistantly around an outer perimeter of the neck portion 54, near the shoulder 55 and raised radially outwardly therefrom a preselected distance.

The bayonets 60 may be integrally-formed with and connected to one another by an annular band 60a raised radially outwardly from the neck portion 54 coextensively with the bayonets 60 along a lower portion thereof near the shoulder 55.

Each bayonet 60 includes an axial upright portion 70 projecting upwardly from the annular band 60a away from the body 52 and an annular overhead potion 72 projecting annularly from said upright portion 70 in a backwardly (that is, counter-clockwise, when viewed from above) direction.

The overhead portion 72 is spaced from the annular band 60a by a preselected distance and terminates in a latch portion 74 projecting downwardly towards the annular band 60a. The latch portion 74 is annularly spaced from the upright porticn 70 by a preselected distance. The annular band 60a, the upright portion 70, the overhead portion 72 and the latch portion 74 are preferably integrally-molded and are raised radially outwardly from the container neck portion 54 by a preselected distance.

The annular band 60a cooperates with the overhead portion 72 of each bayonet 60 tcl define a lower radial recess 62 therebetween. An upwardly stepped portion 61 of the annular band 60a projects axially upwardly therefrom towards the overhead portion 72 and is spaced annularly backwardly from the upr ght portion 70 of each bayonet 60 to define a lug-receiving recess 64 between a lower rail 74a of the latch portion 74 and an upper rail 61a of the annular band stepped portion 61. Where more than one bayonet 60 is provided on the container neck portion 54, the annular band stepped portion 61 may be ir.tegral with the upright portion 70 of each bayonet 60. The lower radial recess 62 communicates with an upper portion of the container neck portion 54 bJ the lug-receiving recess 64, which is sized to slidingly receive one of the at least one lugs 19 therein. The upright portion 70 of each bayonet 60 cooperates with the overhead portion 72 and with the latch portion 74 thereof to define an upturned recessed portion 63 being surrounded on three sides thereof try the raised bayonet 60 and being in communication with the lower radial recess 62.

With reference to Figure 1 and Figures 5-7, a safety closure 10 for use on the container 50 is of an integral construction and includes an end wall 12, a cylindrical skirt 14 depending downwardly from an outer perimeter of the end wall 12, an outwardly-flared continuous annular plug 16 depending downwardly from an underside surface of the end wall 12, and at least one spring member 20 depending downwardly from the underside surface of the end wall 12 (znd d spaced radially outwardly from the plug 16sa a preselected distance. A1-ematively, the at least one spring member 20 may project inwardly and downwardly from the closure cylindrical skirt 14. Preferably, eight spring members 20 are provided and are annularly spaced equidistantly outwardly around an outer perimeter of the plug 16, defining narrow annular spaces 20a therebetween. The safety closure 10 is preferably constructed from any suitable heat-setting, moldable polymer, such as, for example, polyester, polyethylene, polypropylene or the like, and is formed by any suitable process, such as, for example, injection-molding or the like. An outer surface 18 of the skirt 14 may be provided with axial grooves, knurls, ridges, or other surface texttring to pennit easy gripping and rotation of the safety closure 10.

At least one lug 19 is integrally-molded with, and projects radially inwardly from, an inner annular surface of the skirt 14 near a lower end 15 thereof. Mor particularly, one lug 19 is provided for each of the at least one bayonets 60 provided on the container neck portion 54. Preferably, four lugs 19 are provided and are annularly spaced equidistantly around an outer perimeter of the skirt 14 to fit between the bayonets 60, and more particularly, to fit within the lug-receiving recesses 64 defined by the bayonets 60. Each lug 19 is sized and shaped to be slidingly received within the container bayonet lug-receiving recess 64, the lower recess 62 and the upturned portion 63 of the lower recess tri2.

With additional reference to Figures 8 and 9, the safety closure 10 is affixed to the container 50 (and particularly, to the container neck portion 54) by aligning the safety closure 10 with the container neck portion 54 such that the lugs 19 are aligned with their respective lug-receiving recesses 64. The safety closure 10 is then depressed axially downwardly onto the container neck portion 54 such that each lug-receiving recess 64 receives their respective lug 19 therein. The safety closure 10 is then simultaneously moved axially downwardly and radially forwardly (that is, clockwise, when viewed from above) such 1hat the lugs 19 simultaneously travel within their respective lugreceiving recesses 64 and into their respective lower recesses 62. At this point, the annular plug 16 has been received downwardly into the orifice 57 of the upturned portion 59 and thereby forms a sealing fit with an inner annular surface of the upturned portion 59 and with an inner annular surface of the camning portion passageway 62a, which may be provided with a slight inward radial taper downwardly away from the orifice 57 to prevent the plug 16 from becoming stunk therein The spring members 20 depend downwardly from the end wall 12 a sufficient distance (and the lugs 19 are spaced from the end wall 12 a sufficient distance) such that, as the lugs 19 travel downwardly within their respective lug-receiving recesses 64 and into their respective lower recesses 62, the spring members 20 abut an outer surface of the camming portion 56 and are flexed radially outwardly thereby against their natural resilience to remain in a substantially downward orientation. The camming portion 56 thereby provides an .lxially-upward biasing force to the safety closure 10, biasing the lugs 19 upwardly and outwardly of their respective lug-receiving recesses 64 along an angled upper rail 74a thereof define by the latch portion 74. The user prevent'; unwanted lifting and removal of the safety closure 10 from the container neck portion 54 by continuing to apply a downward axial force to the safety closure 10 against the upward bias of the spring members 20 at all times during whidl the lugs 19 are positioned in the lug-receiving recesses 64. If the user removes the downward axial force from the safety closure 10 while the lugs 19 - positioned within the lug-receiving recesses 64, the upward biasing force will lift the lugs 19 away from annular band 60a until the lugs 19 abut the upper rails 74a, at which point the upward biasing force will cause the lugs 19 to slide along the rails 74a upwardly and backwardly, forcing the safety closure: 10 off of the container 50.

Howeo er, once the safety closure 10 has been depressed downwardly a sufficient axial distance such that the lugs 19 are positioned within their respective lower recesses 62, the safety closure 10 is rotated forwardly a preselected distance such that the lugs 19 are positioned axially downwardly adjacent their respective lower recess upright portions 63. In response to the user's removing the downward axial force from the safety closure 10, the upward biasing force provided by the spring members 20 lifts the lugs 19 axially upwardly away from the annular band 60a and seats the lugs 19 within their respective lower recess upright portions 63. Removal rotation of the safety closure 10 is thereby prevented while the lugs 19 are seated within their respective lower recess upright portions 63 by an abutment 69 defined by the latch portion 74 of the bayonet 60.

Removal of the safety closure 10 from the container 50 is accomplished by depressing the safety closure 10 downwardly against the upward biasing force provided by the spring members 20 a sufficient distance to unseat the lugs 19 fronl within the lower recess upright portions 63 and to position the lugs 19 within their respective lower recesses 62. The safety closure 10 is then rotated backwardly a sufficient distance such that the lugs 19 are no longer positioned axially downwardly from their respective lower recess upright portions 63, but are instead positioned axially downwardly from their respective luI,-receiving recesses 64 and downwardly adjacent the angled rails 74a thereof. The user's releasing the downward force opposing the spring member biasing force lifts the safety closure 10 axially upwardly relative to the container 50, thereby positioning the lugs 19 within their respective lugreceiving recesses 64 and to travel upwardly therein along the angled lower rails 74a and off of the container neck portion 54.

The er'gagement of the annular plug 16 with the inner surface of the camming portion 56 provides an efficient, fluid-impervious~seal therebetween which is not substantially negatively affected by flexure of the spring members 20 against the container neck camping portion 56. Because the spring members 20 are separate from the annular plug 16, the annular plug 16 does not need to flex to provide a biasing force, thereby maintaining the sealing fit between the annular plug 16 and the container neck portion 54 during affixing and removing the safety closure 10 therefrom.

With r eference to Figures 10-12, a safety closure 110 according to an alternative embodiment of the present invention is shown affixed to the container 50 according to the preferred embodiment hereof hereinabove described, wherein the safety closure 110 according to the present embodiment includes marly components in common with the safety closure 10 according to the preferred embodiment hereof hereinabove described, and wherein like reference nunerals are intended to represent like components.
